I. Introduction
With the advent of Machine to Machine (M2M), Internet of Things (IoT), and next-generation networks, the demand for data-intensive applications, massive ubiquitous connectivity, and mobile data traffic is expected to increase year over year [1] [2]. This ever increasing demand is a driving force behind Mobile Network Operators (MNOs) continual acquisition of additional spectrum and the densification of their networks to address the demands of their customers and target markets. Due to the limited available spectrum, and decreasing marginal benefits of network densification due to increasing Operating Expenses (OpEx), MNOs are investigating additional sources of revenue and new means of alleviating the demands on their mobile networks. Reselling under-utilized spectrum provides a means of generating revenue, while offloading non-QoS (no guaranteed Quality of Service) services offers a means of reducing the OpEx incurred due to network congestion.
